# Any Formula vs Voltary

The clearest difference is in-app purchases: Voltary at none against Any Formula's 1. Voltary also leads on iOS requirement (13.0 vs 18.0). Any Formula's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Any Formula sells 1 one-off in-app purchase. Voltary asks for nothing beyond the download.
